Software Engineer

At Mantari Industries, we’re replacing yesterday’s public sector weather systems with a full stack, AI-native platform that senses, models, and predicts Earth’s atmosphere and oceans in near real time. Our mission is to sense Earth in its entirety — oceans, skies, and space — and close the gap between what nature does and what humanity knows. By building a distributed network of sensors fused with breakthrough AI, Mantari transforms raw environmental signals into actionable intelligence so that the world’s most critical outcomes, from global trade and securing grids to defending nations, are guided not by uncertainty, but by foresight. Our autonomous edge sensing fleets, deep learning forecast models, and integrated customer decision engines will create the most precise weather intelligence on the planet—empowering industry, strengthening climate resilience, providing vital intelligence to American warfighters, and opening billion-dollar markets that don’t exist yet. Backed by premier venture capital and led by engineers and scientists who’ve landed rockets and pioneered novel AI forecast techniques, we move fast, own the hard problems end to end, and measure success in real world impact. If you want to build frontier tech with outsized consequences, welcome aboard. Description Own the guts of our modeling engine, everything between raw sensor data and a lightning-fast forecast API: Build and optimizeCUDA kernels,JAX/PyTorch ops, anddistributed training loopsforphysics-aware transformer models Stand upreproducible, containerized pipelines(Ray, Kubernetes, Slurm, or similar) that scale from asingle GPUtomulti-region GPU clustersin the cloud Automatedata ingestandfeature engineeringfrom our growing sensor network (satellite,buoy,radar, etc.) Translatenovel research prototypesintoproduction-grade code You’ll work closely with Mantari’sHead of Weatherand AI modeling teams to operationalize next-generation forecast systems, bringing meteorological science and modern ML together atplanetary scale.

Collaborate closely with the founding team and SMEs to push the boundaries of observation-driven AI-native weather forecasting, and turn weather into an advantage, not a roadblock. LA HQ required. Equity upside commensurate with being one of the first core team members. Competitive salary, full benefits, and hardware budget. Weather shapes every decision made on Earth. At Mantari you’ll write code that moves metal, launch sensors that tame storms, and see your work ship in weeks—not years. Join us to build the world’s first private full-stack weather platform and leave your fingerprints on infrastructure that will outlast us all. Apply now—let’s create the future of weather, together.
